cmd/compile: skip substituting closures in unsafe builtins arguments
For unsafe.{Alignof,Offsetof,Sizeof}, subster will transform them them
to OLITERAL nodes, and discard their arguments. However, any closure in
their children nodes were already processed and added to declaration
queue. Thus, we lack of information for generating instantiation for
the closure.
To fix it, just skip substituting the closures if we are going to edit
the children nodes of unsafe builtins.
Fixes #53390
